};
This function can be used to extract the text of a page or template, or to find a specific text that
should be replaced or deleted with the function ReplacePageText() or ReplacePageTextEx().
The structure TPDFStack must be initialized with InitStack() before calling the function the first
time. All members of this structure are read only with the exception of the variables in red color.
These values can be changed after the structure has been initialized with InitStack(). Do not change
the value of another member; otherwise the function causes maybe an access violation!

Description
ctm
The matrix represents the current coordinate system (user space). The matrix is
already pre-multiplied because the function returns only when a text showing
operator was found.
tm
This matrix represents the text coordinate system in which all text properties are
calculated. We call this coordinate system text space. To enable the calculation of
the text position the matrix must be multiplied with the matrix ctm.
x, y
These members are no longer used. All positioning operators are already
included in the text transformation matrix tm.
